Yay! Have been using that it on the N9 quite a bit :) Looking forward to your 
port.

I think you're missing the --desktop_file_hint argument. You must pass a 
.desktop file with each binary to tell Ubuntu to which application it belongs.

./myapp --desktop_file_hint=/absolute/path/to/a/file.desktop


If it still crashes, you should be able to run it in gdb like this. ssh into 
your phone and start up gdb with your binary:

gdb /path/to/binary

when gdb is loaded, run it providing the --desktop_file_hint argument:

r --desktop_file_hint=/path/to/file.desktop

After that, use gdb as usual.

Hope this helps,
Michael
